This is a set of four books by Shunmyo Masuno, whom I discovered through the influence of Yoshihiko Natori, who I discovered through the influence of Masakazu Kobayashi. These are books by authors I encountered while reading the works of Masakazu Kobayashi. As expected, there was a lot of very helpful information. Both Yoshihiko Natori and Shunmyo Masuno are themselves chief priests, and they clearly teach methods of enlightenment based on their extensive experience. Please take a look. These are used books, so please consider purchasing only if you understand that there may be oversights regarding the condition of the books. Please note that returns are not accepted, so I ask that you consider your purchase carefully. Please confirm availability before purchasing, as these items are also listed elsewhere. Thank you for looking! ♪♪♪
